To all whom if. may. concern:

Be it known that l., FRANK isrfrnnson., si citizen of the United States, and a, resident oi" Eden, in the county o3 Williams and Stute of hio.y have invented a certain new and useful Noinltidding Device and Climber for Automobiles; und l do hereby declare the following to be e iull. clear, end exact description oi' the invention, enable others skilled in the art to which it eppertains to malte and use the seme, reterence being had to the accompanying drewings, end to the figures of reference marked thereon, which forni e part of this specificetion.

My invention. relates to Ineens for use pen ticulnrly in connection with automobile wheels for preventing a slipping or shielding of such wheels when traveling over slippery surfaces or when ascending or descending inclines.

rlhe object of my invention is the provision ot e simple and improved device of this cheracterivhich is inexpensive to manufacture, strn'ig` and durable in its construction7 und highly etlicient in its operation, end which is provided with noise deedening meuns "whereby the noise incident to the device striking the surface over which the vehicle running is reduced to a minimum.

T he operation, construction, and arrange ment et the parts of my invention are fully described in the following` speciicetion7 und While the invention in its broader aspect is susceptible of numerous modifications, e preferred embodiment of the sinne illustrated in the accompanying drawings, in Which,-

Figure i u side elevation of e portion of u wheel equipped with my invention. Fig. an enlarged cross-section thereof on the line a; in Fig. l. Fig. 3 is an enlarged side elevation of the bur comprising my invention with the ends thereof es they appear at diierent stages of the shaping process. Fig. 4 is e plan view of the sume in its completed state, und Fig; 5 and 6 are sectional views or such bur on `the lines y y and w and w, respectively in Fig. d.

Referring' to the drawings, l designates en oblong ber or gripping-shoe of steel or other suitable materiel, which is intended to be secured on the treed of e tire transversely thereof. as shown. rthis bar comprises the body portion 2 having e straight outer sursuch es will if'ace longitudinelly conceved inner surte-ce to see-t on the tread of the heel.

tire 3 oit' e vf The straight outer side of the body 2 nrovided neer euch end with i s recess or cavity e, and et the edges thereof l zit cach side of such recesses with outwardly projecting lips or hereinafter described.

Extending longitudimilly from the inner portion oi' each end oi' the body 2 is e. re- .duced neck or shonlr 67 which terminates in e block 7. yThese blocks have their outer and inner surfaces riet and the outer surfaces thereof terminate :it their ends in abruptshoulders 8, es shown. rlhe shanks 6 are intended to be bent outwardly to cooperate Withthe ends ci the receiving e linlr of securing means l0,

e chain or other suitable and to permit the blocks 'T to rest tiet on the end portions of the body 4over the recesses and between the lips or lugs to torni csllrs for the body. The sides oiE the blocks T ure tapered or beveled, l as shown et in Fig. G, to enable Awhen pressed thereaguinst to firmly hold 'such blocks or' culks to the body. The abrupt shoulders S the inrery and Outer ends of the blocks er ve to dig into thefsurfece over which the vehicle may ,be passing to prevent i lateral slippingr thereof?. While the sharp at the side edges .of the tion in u straight 'forward 'r ybackward running' of the vehicle. Y

ln the manufacture of the bers 1 they are preferably but not necessarily, drop forged with the shenlrs e and celk blocks 7 projecting" from the body 2 thereoi es shown at the lett of Fig. rhe ends are next bent to partially close the 9, es indicated :it the right of Fig. 3, to enable the links or chains l0 to be placed in engagement therewith, 'after which the blocks 7 are pressed down upon the body i over the recesses i and between the/lips being firmly held in such position by e compression or clenching of such lips against the tapered sides thereof.

The provision of the noise-deadening recesses 4' beneath the cullrs 7 is found to he quite en important feature in devices of this class7 as it materially lessens the noise due to the use thereof, thus obvieting to iiconsidereble extent one of the principal objections and causes of annoyance incident` to ings 5 for the purpose.

the lips bloclrs give them the necessary gripping ec-V body 2 to form eyes 9 for devices of this character. To a dead air space Within such recesses upper surface of the body 2 is preferably notched as at li, to provide communication between the recesses and the associchain or securing member l() from injury.

rEhe securing members l0 are shown as extending inwardly at the sidev of the tire and connecting to holding c.-ains i2 at the sides of the Wheelrrim, as is common With devices of this class. i

' E Wish it understoodl that my invention is not limited to any specic construction or arrangement of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what i claim as new and desire to secure by Letters Patent, is,- y'

l. A device of the class described, comprising a body part having recesses in the out r surface thereof adjacent its ends, and callrs carried by the body part over such' recesses.

2. A device of the class described, comprising bar adapted to fit to the tread of tire, and callas carried in spaced relation by such bar, said bar and calks coperating to-orm closed noise deadening cavities.

device of the class described, comprising a body part having cavities in its cuter face anc integral projections at its ends which are bent over and rest upon the body at the margin of the cavities and form cailzs .for the body.

d. A device of the class described, comprising body part having projections atl its ends terminating in flat blocks, suc-h projections being bent to' permit said blocks to rest firmly upon the body in spaced relation to form calks.

5, A device of the class described, coniprising a body part having Shanks projecting from its ends and terminatingxin blocks, said Shanks beine bent to form coperating securing eyes and to position such blocks immediately above the end portions of the body part, to forni callrs.

A device of the class described, coinprisinjr body part having a iiat outer surface and having` reduced Shanks projecting from its ends an l terminating in blocks, said shanlrs heik bent to enable-such blocks to rest upon th end portions of the outer surface of the body part to form calks with their inner ends spaced. v f

7. A device of the class described, com-` prising a body part having projections at its ends, the terminals of Which are bent over upon such body part to form calks, and means projecting-from thel body part and coperating with the sides of the calks to rigidly secure them to the body part.`

8. A device of the class described, comprising a body part having projections at its ends, the terminals of Which lare bent over upon the end portions ofl the body artv in spaced relation to each other to crm calks, said terminals having abrupt shoulders at their end portions.

9. A device of the class described, coin-l prising a body part having projections at its ends, the terminals of Which are bent over upon-theend portions of the body part lto form calks, said terminals having their outer surfaces flat and terminating at either end in abrupt shoulders and their side edgesr beveled, and means carried by the body and cooperating with the beveled side edges of the projection to rigidly secure them to thev body part.

10. A device of the class described, comprising a body art having recesses in its outer surface andp projections at its ends, the terminals of which are bent upon the body part over such recesses to form calks for the body part. i

11. A device of the class described, comprising a body part having its outer surface iattened and its inner surface fashioned to conform to the surface of an article on which it is to rest, said body part having projections at its ends which terminate in blocks and are bent over u on the end portions thereof With the bloc is in flat contact therewith whereby to form coperating se# curing eyes and calks for the bod part.

lp.' A- device of the class described, comprising a body part having its outer surface provided with recesses and havingprojec# tions at its ends which are bent over upon the end portions of Athe body to form co'- operating securing eyes and calks therefor, said calks being dis osed over said recesses, and means for rigi ly securing the calks toV the body part.

ln .testimony whereof, I' have "hereunto" signed my name to this specification in th presence of two subscribing Witnesses.
